Police in Detroit, Michigan, say the remains of 11 infants were found in the ceiling of a defunct funeral home on Friday. The discovery came after state authorities received an anonymous letter saying there were human remains in the building.

Officials from the state Department of Licensing and Regulatory Affairs found the infants’ remains in what Detroit Police detective Brian Bowser described as a “false ceiling” between the first and second floors of the building, The Detroit News reported.

The facility had been closed for months due to what police described as “deplorable conditions.”Detective Bowser told reporters nine of the infants’ bodies were found in a cardboard box and the other two were found in a trash bag inside of an infant-sized casket.

Jameca LaJoyce Boone, who The Detroit News said managed the funeral home for a year before it closed, called the discovery “very unfortunate,” and said “I didn’t know anything about that.”
